One significant task when you are making IoT devices is making use of Arduino to help connect Arduino to your internet. The common ways include Lora –here, you will need Lora gateway GPRS/5G/4G/3G ZigBee – Here, you will need a ZigBee gateway BLE or Bluetooth – this requires a Blueto...
This is simple guide on how to connect ESP32 as the client to Arduino Nano 33 BLE sense as the server (peripheral) via Bluetooth (BLE) Description This repository provides documentation and code examples for connecting an ESP32 device to an Arduino Nano 33 BLE Sense using Bluetooth Low Energy...
}Code language:Arduino(arduino) The code at the master device, or the joystick is quite simple. We just need to read the X and Y values of the joystick, which actually regulate the speed of the motors, and send them via the serial port to the slave HC-05...
In that case, once we connect the first Arduino to the computer, we need to select the model and the COM port and upload the code to the Arduino. Then we connect the second Arduino and we have to start the Arduino IDE again in order to be able to select the other COM port to ...
I have a device that has HC-42 Bluetooth 5.0BLE module and I want to connect it via esp32-wroom-32. I found the UUID of the device but there is no characteristic UUID. I've used BLE_client example to connect my HC-42 module but it did not work. Thank you in advance in your he...
The first step that you should take is to make all of the connections to your HC-05 Bluetooth Module. For this I used Female-Male wires to connect it to the Arduino Uno and also to the PCB board. When connecting the Bluetooth Module to the Arduino, make sure that the TX pin of the...
For this robot, we have to connect the Bluetooth module (HC05). In the following figure you can observe where the Bluetooth module’s 6 pin connectors are plugged on evive.Bluetooth module’s RX pin will go to TX3V3 pin on evive and others correspondingly. Note that on powering evive,...
-Arduino Http Client — for interacting with ThingsBoard using HTTP Step 1 In the first step, we have to connect all required hardware. The connection scheme is: Step 2 In order to start programming, we have to download all required libraries. To do this click on Tools > Manage Libraries....

Ensure the Bluetooth is turned on, on the computer When Arduino is connected to the USB port of the computer, RX and TX pins on the HC-05 need to bedisconnected. When RX and TX pins on HC-05 are connected, USB needs to bedisconnected. This prevents HC-05 from interference with the ...
